Malocclusion
Pronunciation: mal-oh-KLOO-zhun
Any deviation from the ideal alignment and bite relationship of the upper and lower teeth, classified using Angle's classification system (Class I, II, III).
Full Definition
Malocclusion encompasses a spectrum of misalignments in the dental arches and jaw relationship, ranging from mild tooth crowding to severe skeletal discrepancies. Edward Angle's classification — Class I (normal jaw relationship with local tooth irregularities), Class II (retrognathic mandible), and Class III (prognathic mandible) — remains the primary descriptive framework used in orthodontic records, referral letters, and medico-legal reports. Editors should ensure that Roman numerals are used for Angle's classes and that subdivision designations (e.g., Class II Division 1) are correctly reproduced.
Usage
Usage note: Always use Roman numerals for Angle's classes (I, II, III) in formal clinical and editorial contexts.
